Fondling his wife, he had an erection and ejaculated while fasting

Q 2: Does an erection due to kissing one's wife render Wudu' and Sawm (Fast) Batil (null and void) or Wudu' only? Another question: What is the ruling on wearing perfume while fasting; is it Haram (prohibited) or Makruh (disliked)?

A: Generally, as a fasting person, you should keep yourself away from acts which render Sawm incomplete or Batil. The Prophet (peace be upon him) is reported to have said: When any one of you is fasting, he should neither have sexual relations with his wife nor behave impudently; and if anyone abuses him or quarrels with him he should say: "I am fasting." (Agreed upon by Al-Bukhari and Muslim) Yet, if you have already ejaculated Maniy (semen), your Sawm is Batil, and it is Wajib (obligatory) on you to make up for this day and do (Part No. 9; Page No. 163) Janabah-Ghusl (full ritual bath to cleanse of sexual discharge).However, if you just kiss (while fasting) without ejaculation, this may lead to emission of Madhy (thin white viscid fluid secreted due to sexual thoughts or desire). Emitting Madhy while being in a state of Wudu' renders it invalid, so you should perform it again after washing the penis, and the testes (if you want to pray), but Madhy does not render Sawm invalid. These rulings are also applied to your wife. As for wearing perfume while fasting, there is nothing wrong with it, but you should avoid sniffing incense. However there is nothing wrong with perfuming clothes and turbans with it (incense).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
